The risk of weeds developing resistance to a herbicide site of action is determined both by how the herbicide is used by the applicator and also by the frequency of resistance mutation in weeds. The more a site of action is relied on, the greater the risk of resistance, regardless of the frequency of resistance.

This publication examines the symptoms and signs of Goss's bacterial wilt and blight of corn, conditions that favor the disease, the disease cycle, and how Goss's wilt differs from other plant problems that may look similar. Information on disease management and yield losses are also included.

European corn borer has been a significant pest of Iowa field corn since the 1940s. This publication discusses the European corn borer life cycle, injury caused to corn and management options with a focus on Iowa field corn production.

Seed treatments for management of plant-parasitic nematodes, including the soybean cyst nematode (SCN), are a relatively new management option. This publication lists and gives some characteristics of the currently available seed treatments for use in managing SCN.

Engage the crop scouting with expertly narrated videos, slide shows, interactive graphs, simulations, visual quizzes and more. This interactive textbook provides a guided learning experience and allows for self paced inquiry and discovery. Crop scouting is an important part of Integrated Pest Management (IPM). Scouting crops helps us to understand what is going on in our fields right now and helps us better understand future issues that may arise. Scouting helps us identify problems such as disease, pest insects, weeds, and other issues; identifying these issues is the first step in implementing management.

This publication shows how to obtain an estimate of the potential yield loss from hail injury to corn. It describes the methods used to quantify injury and stand loss, as well as corn growth stages, which are an important part of the yield loss estimation process. Information on fungicide use on hail-injured crops, replanting severely injured stands, and weed management after hail are also included. CSI

This revised, 158-page pocket-sized guide (3-3/4" x 6") combines the Corn Field Guide and Soybean Field Guide in one publication for ease of use by corn and soybean farmers, agronomists, and crop scouts.

Newly updated text and images provide the tools for identifying insects, diseases, and disorders of corn and soybean in the Midwest. The guide also contains information on developmental stages, pesticide decisions, and other production-related topics. This publication is constructed of durable, weather-safe materials to withstand regular use in the field.

It is produced and distributed in partnership between the ISU College of Agriculture and Life Sciences and ISU Extension and Outreach.

Ticks can be found across the state of Iowa and are active from March through November. This publication discusses the three most common type of ticks in the state while also providing information on preventing Lyme disease and removing attached ticks.

Scale insects are tiny insects that can cause large problems for landscape plants. Despite their small size they can weaken and even kill ornamental plants. This publication provides information on identifying these insects and steps that can be taken to remove them from plants through biological, mechanical and chemical means.

This publication examines the symptoms and signs of sudden death syndrome in soybean, describes how sudden death syndrome differs from several other diseases that may look like it, provides other scouting information, and management recommendations.

The publication was developed by the Crop Protection Network, which includes authors from land-grant universities across the North Central Region and Ontario. CSI

Are you interested in having more bees in your garden? Are wasps buzzing around your pop can? Learn about their life cycles, what they feed on, and where they nest. The behavior and biology of the most commonly encountered wasps and bees in Iowa are described in this resource available from our partners at University of Minnesota Extension.

This resource was a joint project between Iowa State University Extension and Outreach, the University of Wisconsin Extension, and University of Minnesota Extension.

Opening the flour container to find beetles crawling around the top is never a pleasant experience, but there is no need to panic. The most common pests we find in our kitchen and pantries and what we can do to manage them if they infest our food are described.

This resource was a joint project between Iowa State University Extension and Outreach, the University of Wisconsin Extension, and University of Minnesota Extension.

This publication examines the symptoms of soybean vein necrosis virus (SVNV), describes how SVNV differs from several other plant problems that may look like SVNV, and provides other scouting information.

The Speed Scouting for Soybean Aphid card is a tool for soybean growers to monitor soybean aphid populations in fields using the Speed Scouting technique. The card has both instructions for the Speed Scouting process and a worksheet for recording soybean aphid field observations. Observations are then used to determine if treatment is needed. The Speed Scouting card is a collaborative effort of ISU Extension Specialists and the Iowa Soybean Association.

Find out how targeted conservation practices can have the most impact on environmental quality while causing only a small change in overall agricultural production. Environmental benefits are discussed related to clean air and water, productive soils, diverse wildlife and plant habitat, and biological controls for crop protection.

West Nile encephalitis, a mosquito-transmitted disease, was first documented in North America during the summer of 1999, when an outbreak occurred in New York City. Since that time, cases of West Nile virus (WNV) infection have been confirmed in northeastern, north central, southern, and western regions of the United States, and the virus is expected to spread throughout North America.

This two-page handout on West Nile Virus describes virus transmission, the mosquito vector life-cycle, and steps you can take to reduce mosquito habitat near your home and prevent mosquito bites.
